The right roller depends on the specific job. The main types of rollers for cable pulling are:

• Straight Trench Rollers: These are the most common type, used for straight cable runs in open trenches. They prevent the cable from dragging on the trench floor, which can cause significant damage from debris or sharp edges.

• Corner Rollers: These are designed to guide the cable smoothly around bends and corners in a trench or duct. They can be individual units or linked together to form a specific radius, ensuring the cable maintains its minimum bending radius and preventing excessive sidewall pressure.

• Manhole Rollers: These specialized rollers are used at the entry and exit points of manholes and ducts. They provide a smooth transition for the cable as it changes from a vertical to a horizontal pulling path.

• Aerial Stringing Rollers (Running Blocks): While not for underground work, these are also a type of cable roller. They are used for overhead line construction to support and guide the conductor as it is pulled from pole to pole.
